`Application filed May 2, 1922.` Serial No. 557,874.

To all w hom t may concern Be it known that I, Pliner E. AUGHAN,

. a citizen of the United States, and resident of San Jose, in thecounty of Santa Clara and State of California, have invented cer tainnew and useful Improvements in Pumps, of which the following is aspecilcation. j

My invention relates particularly to deep well centrifugal pumpconstruction.

It is the object of my invention to provide a pump construction whereinthe pump assembly and discharge casing column are supported by astructure within the discharge casing column and preferably cnclosingthe pump shaft.

It is another object of my invention to provide a means for suspendingthe pump bowl assembly whereby a discharge casing column of slighttensile strength may be used.

It is a further object of my invention to provide means whereby adischarge casing column supported from its lower end may be subjected tocompression strainswhereby water tight joints are insured.

It is still a further object of my invention to provide a structurewherein the driving shaft of the pump is closed oli" from the water byan enclosing tube, and wherein the enclosing tube supports the pump bowlassembly, and the pump bowl assembly supports a second enclosing tubularcolumn for closing off the water discharged by the pump from the well,

In the drawing Figure 1 is a vertical cross-section through a pumpembodying my invention,parts beingbroken away.

Figure 2 is an elevation of a Vportion of the discharge casing columnshown in Figure 1.

Figure 3 is a cross-section on 3-3 of Figure 2.

Figurelis a vertical cross-section through a portion of a pumpembodying` another embodiment of my invention.

Referring more particularly to the drawing I show at. 1 the well casingof the usual deep well casing construction. At 2 is the discharge headthe base 8 of which has an annular depending flange el formed.integrally therewith, the said flange surrounding a discharge casingcolumn 5 which extends froin the head 2 to the bowl assembly as at 6.

In the embodiment shown inFigure 1 the discharge casing 5 is made up ofa number of longwooden strips shaped as to make an annular tube and heldtogether by the wire winding as T and staples as 8. This tube or casingis made up in this way in suitable lengths which are assembled the pumpisY lowered, by means of the lap joints as shown at 9 which are wound"`with wire l0 to hold the same in place.

At 11 is shown a tube of small diameter which is securelyl fastened tothe bearing bowlQO of the bowl assembly 6 as at 12, and the lengths oftubing are held in align` ment by means of a collar as 13. This tubewhen assembled `extending upwardly through the discharge head and isthreaded into a depending flange la formed inte-y grally with the baseplate 15 of the pulley assembly 1G as shown. This flange 14 beinginternally threaded to receive the tube 11 and is a turning lit in thewall 17 of the discharge head 2. i

The shaft as shown at 18 is connected to the runners ofthe bowl assemblyand eX- tends upwardly through tube 11 to the pulley 19 as shown.

The bearing bowl 2O ofthe bowl assembly 6 has its upper end turned outas at 21 to receive the discharge casing 5, a rub,- ber gasket as 22being inserted between the discharge casing `and the bearing bowl asshown.

The line of shafting 18, shaft enclosing tube 11 anddischarge casing 5having been built upto the top of the well a rubber gasket 23 is placedupon the upper end of` the discharge casing and the discharge head i putin place thus bringing the liange al. down overe the discharge casingand the gasket as shown making a watertight joint. The pulley assemblyis now threaded onto the shaft enclosing tube 11 andthe same is drawn upas far as possible by turning the pulley assembly, then the dischargehead and pulley assembly are bolted together as shown.

Thus it is seen that the entire bowl assembly 6, and the dischargecasing 5 are all held in alignment by means of the shaft enclosing tube11. The drawing up of said tube holds the discharge casing tight againstthe bearing bowl 2O and the discharge head 2 as well as keeping thejoints 9 together making the same perfectly water tight. This casing 5however does not sustain any weight whatever, the whole weiglit beingcarried by said tube ll as disclosed.

In the embodiment shown in Figure 4 the discharge head 2 has its baseportion 3 threaded as at 24 to receive a short length of metal dischargecasing as at 25. At 26 is shown the metal discharge pipe column, theseveral sections of the same being oined together from the bowl assemblyto this point as at 27. A space as 28 being left between the upper endof the last section 26 and the lower end of the discharge head section2.5. Y

At 29-30 is shown an annular flange member having' an inner diameter ofslight ly larger size than the outside diameter of the discharge casingas at 3i. The fla-nge 29 being placed over casing 26 and then a 'rubbergasket member 32 shaped as shown is placed on the lange, a cylindricaltube 33 is slipped over the said casing and its outturned end slips overthe rubber gasket as shown. The upper end of tube 33 is also out-turnedand a second rubber gasket as 34 is placed thereon 'and over this gasketis placed the other flange 30, the two flanges being connected by boltsas 35 which are drawn up as tightly as possible, thus forcing the rubberin bet\ Yeen the cylinder 33 and the walls ci discharge tubes 9.5#26vthus forming a perfectly water-tight joint but atthev same time doingaway with any `'support of casing 26 by casing The said 'casing i6 andthe pump bowlassembly being carried by the shaft enclosing tube 11 asstated above.

Thus it is seen that I have provided al pump assembly wherein thedischarge casing itself "carries no weight, the same being supported bya structure within the same, thus allowing the use of a discharge casingoi slight tensile strength which is subjected to compression strainswhereby water tight joints therein are assured. Ot course when a metalcasing is used as shown in Figure 4, the column is not subjected tocompression strains and water tight joints of any approved ;t'orm isused.

'It is to be understood, ot' course, that while I have herein shown 'anddescribed the preferred rembodiments 'of my invention that rhanges maybe made in construction, pro- Jortion, method ol operation 'andmaterials used within the scope of the appended claims.

1. A pump including a discharge casing column, a bowl supporting saidcolumn, and supporting means 'for said bowl arranged within said column.

.2. A pump including ay discharge casing column, a bowl supporting saidcolumn, an iinpeller within said bowl, a driving shaft for said impellerwithin said column, and a column enclosing said shaft Within saiddischarge casing column and supporting said bowl.

8. A pump including a pump head, a discharge casing column slidablyconnected thereto, a pump bowl supporting said discharge casing, and ashaft casing column supporting said bowl.

4.. A pump including a pump head and a pump bowl, a discharge casingcolumn slidably connected to said head and bowl, clastic gaskets betweensaid casing and said head and bowl, and supporting means for said bowl.

5. A pump including a pump bowl, a discharge casing column slid-ablyconnected thereto, and supporting means attached thereto within saiddischarge casing column.

6. A pump including a pump head and a pump bowl, a discharge casingcolumn slid ably connected to said head and bowl, and supporting meansfor said bowl.

7. A pump including a pump head and a pump bowl, 'a discharge casingcolumn inserted therebetween, supporting means for said bowl within saidcasing, and a televscoping ljoint in said column between said head andbowl.

8. A pump including a pump head, a pump bowl, a discharge columncomprising annularly arranged 'wood stares and means for binding thesame togethersupported by said bowl and having sliding 'connection withsaid head, and Supporting means for said bowl within sai'd column.

The method of building a pump which consists in providing a supportingmeans, mounting a bowl and impeller thereon and lowering the saine intoa well, and building up a continuous wood discharge column on said bowlas it is lowered into the well.
